Background: The risk of stroke in individuals with Sickle Cell Anaemia (SCA) can be assessed by routine non-invasive measurement of their cerebral blood flow using a Transcranial Doppler (TCD) ultrasound scan. This study aimed to determine the difference in blood flow velocity parameters in the middle cerebral artery (MCA) of children with sickle cell anaemia compared to a normal age-matched population.

Methodology: This was a hospital-based comparative cross-sectional study among 40 SCA patients aged 3-16 years, in steady state and 40 age and sex-matched HbAA healthy subjects.

Introduction: First trimester pregnancy is defined as twelve weeks after the last menstrual period. Ultrasonography has revolutionized validation and management of first trimester pregnancies. The aim was to analyze ultrasonographic findings of first trimester pregnancies in University of Uyo teaching hospital (UUTH), Uyo, Nigeria.

Background: Observation has shown a preponderance of irrelevant, unjustified and perhaps unnecessary radiological requests in the study area. The consequences of this on the patients' doses and population collective dose may be dire.

Objective: To assess Clinicians/Referrers' knowledge of radiation doses of patients undergoing radiological examinations.

Honey is used in most places as food sweetener and antibacterial agent for wounds. The antibacterial property of honey depends mainly on its peroxide value and acidity. This study investigated the possible effect that may be observed on the peroxide value and acidity if honey is exposed to x-ray at varying tube current values (mAs) in order to infer the possible implications of referring patients undergoing honey therapy for diagnostic x-ray examination.

Introduction: Cases of conjoined twins occur so rarely that it is important to learn as much as possible from each case.

Case Presentation: We present a case of 9-hour-old, female, Nigerian dicephalus parapagus conjoined twins discordant for anencephaly diagnosed only after the birth of the twins. The anencephalic twin was stillborn while the normal one died within 9 hours of birth from cardiopulmonary failure.

Few types of blood exposures have been assessed in relation to incident HIV infection in sub-Saharan Africa, despite evidence that penile-vaginal sex cannot account for the epidemic in the region. To investigate correlates of incident HIV infection in Calabar, Nigeria, we surveyed clients at voluntary HIV counselling and testing centres. Participating clients who tested multiple times were generally similar to those testing only once in terms of demographic characteristics, sexual and blood exposures and HIV prevalence.

Background: The need for the development of criteria for the referral of patients for radiographic examinations, especially in the face of the results of separate studies on temperature and radiation effects, formed the background to this study. The aim of this study is to determine the possible consequences of low dose radiation to living tissue in the presence of elevated temperatures, with a view to developing referral criteria for patients scheduled for radiodiagnostic examinations.

Method: A two part procedure in the form of x-irradiation of water phantom at temperatures ranging from 25 and 45 degrees Celsius, to assess absorbed dose with temperature variation, as well as histological study of living tissue extracted from the skin and lungs of experimental animals, exposed to x-radiation at kilovoltage range between 50 and 90 and temperature values between 25 and 45 degrees Celsius.
